Specification of Letters Patent.

Application filed April 27, 1918. Serial No. 94,024.

To all whom-5t may concern:

Be it known that I, CARL EIBYE, a citizen of the United States, and a resident of Dorchester, in the county of Suffolk and State of Massachusetts, have invented an improvement in Water-Gages, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to gages for indicating the water level in locomotive boilers and for other purposes.

The character of the invention may be best understood by reference to the following description of an embodiment illustrating the invention shown in the accompanying drawings, wherein,

Figure l is a front elevation of a gage shown herein as illustrating the invention;

Fig. 2 is a rear elevation of the gage;

Fig. 3 is a longitudinal section taken line 33 of Fig. 1;

Fig. i is a transverse section taken on line 4-4 of Fig. 1; and

Fig. 5 is a transverse section taken on line 55 of Fig. 1.

Referring to the drawings, the gage shown therein comprises an elongated container 1 having necks 3 at opposite ends thereof tapped to receive pipes 5 and 7 for connection with a boiler or other receiver. The'front of the container has an elongated aperture over which is seated a glass prism 9, a suitable gasket 11 being interposed between them. To enable the water level to be readily disclosed, the glass may be provided on its inner surface with usual facets 13 which render the water level clear cut and distinct.

To secure the glass tightly to the container a frame 15 is provided formed to receive the glass and a. portion of the container. To permit the visualization of the water level thi ough the glass, the frame may have an elongated aperture 17 opposite the elongated aperture of the container. A suitable gasket 19 may be interposed between the frame and the glass.

To press the container and frame toward ezieh other, there are provided yokes 21 straddling the container and having terminals adapted to be connected with said frame. To accomplish this, the latterhas' ears 23 projecting laterally from opposite s1des thereof having eyes registering with eyes 1n said yokes. Pins 25 areadapted to pro ect through said eyes and detachably connect the yokes with said ears. The upper ends of these pins ma be bent to limit downward movement of t e pins as shown in Fig. 2. v

Screw bolts 27 are tapped into the yokes and have ends adapted to bear, against the back of the container. These screw bolts may be setup-to secure the parts together with the necessary tightness, and may be readily released when it is desired to open the yokes and substitute anew glass for an old one.

The features of the gage thus far descrioed are similar to those shown in my application for Letters Patent of the United States, Serial No. 788,348, filed September 5, 1913. Some objection to this form of gage has hitherto been experienced owing to the tendency of the portions of the frame at the sides of the sight aperture thereof, to spread if the screw bolts are set up to place the yokes under too great tension. This distortion of the frame tends to increase the liability of the lass to crack and invites leakage. The sides of the frame and Fatented May as, acre.

container of the gage shown in said appli- I cation abut against each other substantially at points 28 within the lines of tension w-a2 extending from the points of engagement of the screw bolts with the back of the container, to the centers of the pins 25. Ohviously. when the screw bolts are tightened since the abutting points of the contains of ribs 29 which may conveniently be continuations of the ears 23. These ribs project rearward substantially to the, back of the container and the latter is provided with therewith. The opposed ribs on the franie opposed ribs 31 for hearing engagement and container may be convenien'tiy arranged in pairs corresponding to and on opposite sides of the yolres.

The ribs for the frame and container abut at points adjacent their rear ends on line yy and e substantial distance outward beyond the yoke tension lines w-.n referred to, consequently, when the screw hole are tensinned a strong moment of force will occur which, instead spreading the portions 15" of the frame at the sides of its sight opertnre, will tend to draw said portions toward one another, there 3* preventing distortion oi the frame and preventing leakage and smoking of the glass.

The construction referred to not only pie vents the CllSilQliOIl of the frame, but sirably contributes to the general strength. of the Also it eliminates the necessity for the bar shown in said application extending across and obstructing a portion the signt aperture of the frame midway etween the ends thereof. The improvement renders the entire length of the spertnre available to disclose the Water level.

Having described one illustrative embodiznent or" the invent seine thereto, whet I ciaini as new and desire to secure by Letters Patent is:-

l. A gage comprising in combination, a container, a frame having a sight aperture, a glass between said container and frame, yolres straddling said container, pins entered through said yokes and frame, screws tapped into said yolzes engaging the heels of said container, and ribs on said frame and con teiner bearing against each other at points outward beyond the lines of strain from said so ewe to said pins, to tend to draw the per- 1 'tions of the free" eat the sides of said tore inwerdiy.

:2. A gage comprising in combination, n container, 21 frame having a sight aperture, e glass confined between said frame and container, a yoke, means connecting said yolze and frame, screw HLGHES cooperating with yoke to draw said container ililtl i lillllfi toward each other, and elements for said frame. and container bearing against each at points to cause said SCl'BW inenw:

1011 without iiiniting the eon-ens to "tend to draw the portions of the frame atthe sides of said aperture inwardly.

3. gage comprising in combination, a container, a frame having a sight aperture, a glass confined between said frame and contain r, syolre, means connecting said Yoke and frame, screw means cooperating with said yoke to draw said container and frame tow-o1"- other, and means eoopeg 'ating n'th said parts tending to drew the portions name at the sides of said aperture o. L gage comprising in combination, a inc a frame having a sight aperture, :1 confined between said frame and container, means for pressing said frame and cont: r toward each other, and means cooperating therewith tending to draw the glass confined between said frame and con-i tniner, 1i series of yolies, means cooperating L-l1c'en*itl1 for pressing said container and i'inn town d each other, and opposed abutments on said frame and container adjacent .'d yoires to prevent spreading of the p01- s of the frame at the sides of said sperxze comprising in combination, a s frame 15 having a sight spergless 9 confined between said ntoiner, securing means 21, 23, Wing sold frame and container nether, and means 29, 31 to preseeni'ing means from distorting whereof, I have signediny oinention.
